fix(test): repair GlobalTaskList memo re-render test

React.memo blocks root.render() re-renders when props are unchanged,
so storeState task updates were invisible to the memoized component.
Switch useStore mock to a subscription model (useState + useEffect)
so notifyStoreUpdate() forces a proper re-render in the expansion test.
